CALVIN Q. HAYES, OF CHICAGO, ILLINOIS.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 525,268, dated August 28, 1894.

Application filed May 23,1894. Serial No. 512,227. (No model.)

To all whom it may concern.-

Be it known that I, CALVIN Q. HAYES, of Chicago, in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Hydrants; and I do hereby declare the following to be a full, clear, and exact description of the invention, such'as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improved bydrant; and the object of the same is to provide an improved check valve clamp for turning the valves in hydrants and street water boxes.

The invention consists in the novel features.

extends down to the service pipe B having the check valve 0 therein which has the T- shaped turning stem D. In order to turn this valve from the upper end of the box A I provide the vertically recessed head E having the upwardly diverging curved slots F cut transversely therein and adapted to move in said slots are the catch pins or clutches G'- Extended upward from the head is the rod H operated by handle I at its upper end. The said head and rod are positioned permanently in the water box, and when the head is to be attached to the T -shaped turning stem D it is forced down until the movable catches G come in contact therewith and the continued downward movement of the head forces the catches upward in the curved slots and this upward movement separating them permits the stem to pass therebetween, when the catches will at once return to the bottoms of the slots and beneath said stem so that the latter is securely bound in the head and from which it cannot slip. The head fitting over the stem acts as a wrench and when turned adjusts 5 o the cock to the position desired for turning either on or ed the water. By using this sim- The head may be formed as shown in Fig. l

3 with but one sliding pin for engaging the head, and when this construction is'used the device is more simple and quite as effectual in performing its function.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a service pipe, a valve therein having a stem, an operating rod, a head at its lower end having upwardly extending diverging slots, catch pins movable in said slots which are adapted to engage the valve stem in the manner shown and described.

2. The combination of a service. pipe,'a valve therein having a T shaped stem, a head. having upwardly diverging slots, catch pins movable therein for engaging the said stem in the manner described, and a rod extended from the head, substantially as specified.

3. The combination of a service pipe, a valve therein having a stem, an operating rod, an upwardly recessed head on the lower end of the rod which is adapted to fit over the valve stem, the said head being formed with 8 upwardly extending diverging slots on its opposite sides, and catch pins extending across the recess of the head and adapted to move in said slots when engaging the valve stem in the manner shown and described. In testimony whereof I afiix my signature in presence of two'witnesses.
